Found this little tank sitting around collecting dust. Forgot I had it. I don't have the "timing nut" that came with it, but I know I wasn't using because it didn't work. I was just using a good old crush washer along with the black spacer piece in the pics, but additional thin spacers (like the silver ring in the one pic) work as well.
